The one thing I can do is confirm that the Switch version has these improvements that the Wii version had over the GameCube version of Pikmin 1.
-Manually selecting which color of Pikmin to throw
-An overhauled save system that let the player rewind to previous days
-Improved yellow Pikmin AI to make it harder to accidentally die from bomb rocks
-Pikmin thrown at pellet posies will automatically pick up and carry the pellets
-The end of day cutscene can be skipped (this one was in the PAL gamecube version)
-The display showing the number of Pikmin carrying an object matches the color of the onion they're carrying the object back to
I can also confirm it has limited, optional motion controls: turn them on in the options, and you can aim where you'll throw the Pikmin while you hold down the A button. As soon as you let go of A, however, the motion controls do nothing.
